The PCB manufacturing process is not standard and is heavily dependent on design parameters. A low-component-density PCB could be implemented in a two-sided (two-layer) fabricated PCB, which does not ...

Conventional PCB fabrication (raw PCBS) utilizes subtractive copper etching to produce circuitry. This process is generally carried out in a number of steps, as shown in Figure 6.6, where different me...

There are many steps in the manufacture of printed circuit boards (PCBs). They include the preparation of the components and the fabricated PCB, the placement of the components or their insertion into...

Typically, PCBs account for 90% of the total material cost of an electronic product. Developing PCB cost models can vary depending on the accuracy level needed. Consumer products are sensitive to cost...

Both six sigma and the quality loss function discussed above are useful tools that can be used to achieve an assessment of product quality- in design and manufacturing and relate it to the cost of the...

An example of the quality problems that occur in the fabrication of printed circuit boards (PCBs) is the fit of a PCB edge male connector into the product housing female connector or “card cage”. If t...

The quality loss function was defined by Genishi Taguchi, its major author, as “the financial loss to society imparted by the product due to deviation of the product’s functional characteristic from i...

The impact of using quality metrics such as six sigma is that they develop a good accounting of defect causes in the product but do not show the impact of the cost to the company. Several attempts to ...
